The Silka Brand

Calcium silicate units have proven themselves in use over decades and are among the most traditional building materials. The beginnings of their production and initial application go back to 1898. The calcium silicate block, a classic among building materials, today continuous to enjoy tremendous popularity.

Silka is the latest brand in the Xella product portfolio. Initially introduced in Poland in 1995, Silka has since become the international brand for the calcium silicate activities of the Xella Group.

Through its high pressure resistance, even the thinnest walls made of Silka calcium silicate units are highly resilient. Non-combustible, frost-resistant, weatherproof Silka calcium silicate units offer an optimal solution to ensure the stability and longevity of buildings.

Sound in the form of noise is one of the few elements of structural physics occupants can directly sense. As a result of high bulk density, Silka calcium silicate units are exceptionally sound-absorbent, guaranteeing a quiet, relaxing living environment.

Manufacturing calcium silicate units requires comparatively little energy. The production process is environmentally friendly, causes no noise pollution, and is not otherwise hazardous to health. Sand and gravel pits can be recultivated after mining or used as natural habitats or recreational areas.
